me falto esta :v plox​

Answer 1

Respuesta:

Explicación paso a paso:

$8^{0} +7^{-2} \\1+\frac{1}{7^{2} } \\\frac{7^{2}+1}{7^{2} } \\\frac{50}{49}$

$\frac{8m.n^{2} }{m^{-3}n } )^{-2}. \frac{n^{5}z }{4m} \\(8m^{4} n)^{-2} .\frac{n^{5}z }{4m} \\8^{-2} m^{-8} n^{-2} .\frac{n^{5}z }{4m} \\\frac{1}{64m^{8} n^{2} } .\frac{n^{5}z }{4m} \\\frac{n^{5}z }{256m^{9}n^{2} }$

$a^{8}a^{-y}  \\a^{8} .\frac{1}{a^{y} } \\\frac{a^{8} }{a^{y} } \\a^{8-y}$
